Got the kit yesterday. Today was first day of assembly. I went down to local shop and had the o2 sensor welded on for a whopping $20, then started to fiddle with the adapters.
The clifford manifold 4 barrel adapter has 4 single holes, one for each barrel. I had to cut the center "cross" out, because the adapter that came with the kit converted holley 4 barrel pattern to gm 2 barrel tbi, which had the barrels centerd. So just as I was putting it together my pops comes along and tells me why dont you just drill the clifford manifold pattern into the plate that came with the tbi kit, so you only need one plate. The thought had crossed my mind but I didn't think I could drill that straight enough to tap it. But duh, the plate doesn't need tapping the threads are within the manifold itself.
So after all that cutting and mess to the clifford plate (I didn't have a bandsaw, I used a combination of hacksaw, diegrinder, angle grinder, and dremel) the holes were drilled in the howell adapter plate and it went on. The throttle body went on fine, and linkage fit well. The only downside is in certain spots I only have about an 1/8" of gasket material width with metal under it, but I realized that that was also true when I had the clifford adapter with my holley 390cfm carb. In the future, I may get another throttle cable so I can turn the body sideways with injectors parallel to the engine for better fuel distribution. Next up is getting the harness in the car, then installing the pump/fuel lines. Here are some pics of what the engine bay looks like now
